Ahhh...the Lehigh Valley...you're making me sad.
I'm a born and raised Philly area person, lived there well over 40 year. Even wearing a Philly t-shirt right this second. We lived at the southern end of the Lehigh Valley from 2004 to 2014, and I absolutely LOVED it. We now live in Atlanta. I like it OK here, as I'm happy to never...ever...see snow again. But beyond that, I miss home badly.
There is one local station, WFMZ. I'm not sure if you can get it via digital antenna...never tried. Yes, the Philly stations cover the area. Personally, I was a Channel 6 Action News person myself.
As for snow, it will really depend. Some winters are brutal...that's what finally drove us to leave and head south. Then again, some winters aren't as bad. Remember that you're at the foothills of the Pocono Mountains, so you're more likely to get snow. When storms pass through the Philly area, it's very common for the Lehigh Valley to get the most snow. If Philly gets 4", then Lehigh Valley gets 7". Storms can range anywhere from just a little dusting of snow to as much as 18" in one day. Not common, but a big Nor'easter can drop 24" of snow. The last winter we were there, which was '13-'14, was brutal. We had two Nor'easters in one week. We lived in a pretty rural area, with lots of open land, so there was a good amount of wind. In the wind driven areas, even after the storms, there was only a few inches of snow. But in the spots where it drifted, the snow was literally between 4' and 5' deep. I had a Mazda Miata parked outside and it was literally completely covered. Temps were also around -4 at night with daytime highs around 8. That was without the wind, windchill factor was around -15. That's not as common, but very much can happen. But a few years prior, we only had about 6" of snow the entire winter. "Normal" winter will probably bring around 24-30" of snow total for the entire season. Average temps will be 30-38 at the high and 20-25 at the low (during the coldest part of winter). Snow can come as early as Halloween...I think it was 2013 when we had 6" of snow on Oct 29th...knocked power out for 6 days. But that's very uncommon. Mostly snow will start after Thanksgiving and can last until mid-March. If you haven't driven in the snow, I'd highly, highly recommend having someone take you to an empty parking lot and practice. There's no magic to it, but you need to know what you're doing. First and foremost, if your car has ABS (and all cars built in the past 10-15 years do), and you have to stop quickly, stomp on the pedal and hold it down. There was an old way of doing it, which was to pump the brakes, but do NOT do that in a car with ABS. Stomp the brakes and steer.
Not sure where in the south you're from, but the Lehigh Valley can be pretty rural. I'd stay away from Allentown itself, most areas downtown are dumps. But the areas outside of it are very pretty. Lots of small towns, situated right next to each other. The town we last lived in, East Greenville (well, that was on my mailing address, but I was closer to a town called Barto), was a very quaint little town. Lots of open farmland, open spaces, peace and quiet. Had the quintessential downtown "Main St", with tiny local shops and such. My wife and I used to love getting a cup of coffee and walking up the street. The area had a hometown Halloween parade. The local towns would all have their fire trucks, local clubs, etc...complete "small town USA" stuff. Yet, still plenty of civilization nearby...Wal-Mart, grocery stores, etc... Make sure you look into property taxes, they can vary widely.
Tell me what town specifically you're looking at and I can tell you more about it.
